Jim Carrey's ex-girlfriend Cathriona White was reportedly found with pills next to her body.
The Los Angeles Coroner's Office has also confirmed the Irish beautician, 30, who died at her home in Sherman Oaks, California on Monday (28.09.15) from an apparent suicide, left a note at the scene that mentions the 53-year-old actor's name.
Assistant Chief Coroner Ed Winter told 'Entertainment Tonight' that wasn't sure whether the letter was directly addressed to the 'Dumb and Dumber to' star because he had not seen it.
The on-again, off-again couple first started dating in 2012 after meeting on a film set, but split a few months later.
They rekindled their romance last May, but recently ended it for the second time.
An autopsy has not yet been carried out and toxicology results are expected to take eight to 10 weeks to determine Cathriona's official cause of death.
Jim previously paid tribute to the brunette beauty, who moved to LA from her native Co. Tipperary, Ireland in 2009, in a statement, saying: "She was a truly kind and delicate Irish flower, too sensitive for this soil.
"My heart goes out to her family and friends and to everyone who loved and cared about her."
The late Robin Williams' daughter Zelda, who Cathriona occasionally communicated with using the Twitter handle @littleirishcat, also shared her sorrow on the social media site, writing: "Heartbroken to continue to watch sweet, kind souls be consumed by darkness. May it never hurt less, so we never grow numb to the loss.
"In honour of @littleirishcat, please check out http://www.pieta.ie. They do great work in her wonderful home country. RIP Cat."
Robin committed suicide at his home in Tiburon, California in August 2014.
